- Fixed some minor bugs.
- Added a new feature called 'MapOnScalarClipWithRotation' that clips a two-dimensional data with a scalar value and subsequently rotating it to create a three-dimensional effect.
- Corresponding examples, test cases and documentation of the new module have also been added.

- Fixed a minor bug in the Velocity module.
- Added the Rectangle module which enables rectangles to be created.
- Added corresponding examples and test cases for the Rectangle.
- Updated the guide and necessary epydocs.

- Fixed a minor bug in the Camera module.
- Added some extra capability to the Movie module.
- The Camera module now has the capability to perform parallel projection by calling the 'parallelProjectionOn' method.
- The Camera at this stage is only capable of zooming towards the rendered object using 'dolly'. However, it appears that 'dolly' cannot be used to perform zooming out.

Updated more epydocs and the user guide. At this stage, a DataCollector should only be used to read either point data or cell data but not both. If both point and cell data are read using the same DataCollector, the object rendered may be incorrect.
